Hal Finkel 4e05788cc3 Update PEI's virtual-register-based scavenging to support multiple simultaneous mappings ... The previous algorithm could not deal properly with scavenging multiple virtual registers because it kept only one live virtual -> physical mapping (and iterated through operands in order). Now we don't maintain a current mapping, but rather use replaceRegWith to completely remove the virtual register as soon as the mapping is established. In order to allow the register scavenger to return a physical register killed by an instruction for definition by that same instruction, we now call RS->forward(I) prior to eliminating virtual registers defined in I. This requires a minor update to forward to ignore virtual registers. These new features will be tested in forthcoming commits. llvm-svn: 178058		2013-03-26 18:56:54 +00:00
